ROTARY HARRow.

SPECIFICATION forming part of Letters Patent No. 294,112, dated February6, 1884.

Application filed November 9, 1883. (No model.)

.To @ZZ whom it may concern,.-

. with the draft-beam.

Beit known that I, DAvID W. BROWN, a citizen of the United States,residing at Buckhannon, in the county of Upshur and State of WestVirginia, have invented certain new and useful Improvements in Harrows,of which the following is a specification, reference being had thereinto the accompanying drawings.

My invention relates to revolving harrows; and it consists in theconstruction combination, and arrangement of the several parts, as willbe hereinafter described and claimed.

In the drawings, Figure l is a plan view, Fig. 2 a front elevation, andFig. 3 a side elevation, of a machine constructed according to myinvention; and Fig. 4 is a detached sectional view on line x w, Fig. 1.

The harrow A is composed of the beams a, crossing each other, as shown,and provided with suitable teeth,a. The harrow is preferably inade inthe approximately circular form shown, in order to render the revolutionthereof smoother and easier in the operation of the machine presentlydescribed.

The bearing base-plate Bis secured by screws or otherwise on the harrow,at the center of the latter. It is provided with the upwardly-pro jectedshaft or pintle b, which is threaded on its upper end to receive theretaining-nut hereinafter described.

The draftbeain C is provided midway its ends,on its under side,with themetallic bolster G,which is beveled on its under side from its center toits opposite ends. This bevelor inclination is made for the purpose ofreducing the bearing-surface of the said bolster on the bearing-plate Bbefore described. Avertical pivot-opening is formed centrally throughthe bolster and the draft-beam, which are placed' down on the pintl'e,as most clearly shown in Fig. 4. Theparts are secured by nut b,whichbears'preferably against the interposed washer b2.

The drivers seat D is supported on springs D,n1ounted on the draft-beam,and a suitable foot-rest, D?, is provided, as shown.

Furrow-shovels E are supported on the underside of bar F/,which isconnected by rods e rllhe rods e are of such length as to support thebar E beyond the edge of the harrrow,where it operates in rear of thedraft-beam. The said rods e, being connected with eyes e in the mannershown, enables the vertical movement of the bar E necessary foradaptation to inequalityin the ground surface; yet it (the connection4with the draft-beam) is such as to prevent any lateral displacement ofthe furrow-bar and hold same at all times in rear of the draft-beam. Y

`The hitching-rods F F have their rear ends made fast to the draft-beamclose to and on opposite sides of the center thereof, as most clearlyshown in Fig. l. These rods are made of equal .length and extend forwardfrom the draft-beam to a point beyond the harrow, and are bent at theirforward ends to form hooks to facilita-te connection with thedouble-tree G. Near the outer ends of the draft-beam I secure theguyrods ff. The connection of the guys with the draft-beam is pivotal,so the said guys may be swung across to bring their forward endsadjacent the forward end of the corresponding bitching-rods, and arealso bent to form hooks on their forward ends. Ff are arranged onopposite sides ofthe beams pivotal center; so, likewise, are the rods Ff, the said rods Ff and F f being used in conjunction in the mannerpresently described.

The double-tree G has an eye, g, to which are connected the hitching andguy rods.

In practice, when it is desired to have the harrow revolve in onedirection-say that indicated by arrow in Fig. l-the hitch-rod F on theside of the pivot corresponding to said direction andits guy-rod f arecoupled to the eye of the double-tree, and the line of draft on theharrow is such as to cause its revolution when dragged over the groundin the directionindicated. Vhen it is desired for the harrow to revolvein the other direction, the other hitch and guy rod are connected withthe doubletree, as will be readily understood. Then no revolution of theharrow is wished for, the two hitch-rods are passed through a hook orstaple, H, secured on the outer edge of the harrow, and connected withthe double-tree,whereby a straight draft ishad. This overcomes thepositive revolution of the harrow caused by the devices above described,and any involuntary revolution is prevented by the connection with rIherods y the harrow through the hook or staple, as set forth.

It will be seen that where so desired a single central hitch-rod couldbe employed and the different lines of draft secured by the guy-rods.Iprefer,however, the use of the two hitch-rods, as therebya betteraction is secured. This revolution of the harrow in one or the otherdirection, at will, is desirable, as is well understood. By it theharrow will follow the direc'- tion of draft of a team on a hillside,and will not work or slide down the hill. The draft of the hammer isalso rendered much lighter by the revolution thereof. The furrowers orshovels are so arranged with reference to the harrow that the lap of thelatter will regulate the distance between rows. Any number of theseshovels may be used, and, where so desired, may be adjustable alongtheirsupporting-bar. I prefer the number and arrangement of shovels shown.

Having thus described my invention, what I claim, and desire to secureby Letters Patent, 1s

l. In a rotary harrow, the combination, sub- I stantially as describedand shown, of the' harrow, the draft-beam pivoted centrally thereon, thedraft-bars secured to the said'beam, and one on each side of and nearthe center thereof, and the guy-rods securedto the draft-beam near theopposite outer ends thereof, as and for the purposes specied. Y

2. The improved rotary harrow herein described, composed of the harrowproper, the draft-beam pivoted centrally on and supported thereby, thedraft-bars F F, secured to forward side ofthe draft-beam and near to andon opposite sides of the pivot thereof, and the guyrods, secured onenear each end of the draftbeam, the bar E provided with shovels E, andthe rodse e, connecting' said bar E and the beam C, all substantially asand for the purposes specified.

In testimony whereof I affix mysignature in presence of two witnesses.
